Description

Technical Field

[0001] The present application relates to the technical field of air knives, and in particular to an integrally formed aluminum alloy air knife. Background Art

[0002] At present, air knives have a large number of applications in the industrial field such as air blowing to remove water and air blowing to remove dust. Air knives are used to blow away dust and moisture on flat surfaces such as steel plates and aluminum alloy profiles, blow away moisture on the surface of bottles such as beverage bottles and packaging cans, blow away impurities and dust on the surface of products, residual liquid, moisture on the outer packaging, and clean conveyor belts.

[0003] According to the announcement number: CN103206846A, a wind knife is disclosed. This technology discloses "including a first-level air duct, a second-level air duct and a third-level air duct, all of which have a circular inner hole, and the tube body has an air outlet parallel to the axis. The technical solution is that high-pressure air is injected into the inner cavity of the first-level air duct through the air inlet ducts at both ends of the wind knife. The high-pressure airflow is ejected from the air outlet of the first-level air duct and enters the cavity formed by the first-level air duct and the second-level air duct. After a circle, it is ejected from the air outlet of the second-level air duct and then enters the cavity formed by the second-level air duct and the third-level air duct. After another circle, it passes through the air outlet of the third-level air duct, passes through the air filter plate, and enters the air outlet channel between the upper and lower air nozzles to form a stable airflow, which is evenly blown out at high speed from the outlet to form a thin, high-strength, large-airflow impact air curtain. At this time, the airflow pressure ejected from each point at the air knife outlet is uniform, which can ensure relatively stable and high-efficiency output and other technical effects."
